Update ngv test to use V10 emodels (#183)

## Context
Following the update of ngv/metabolism MOD files
(BlueBrain/neurodamus-models#14), the v10
emodels should be used in the ngv test. This PR updates the ngv test
config file in the neurodamus unit tests.

## Scope
Update `tests/simulations/ngv/circuit_config.json`, the same as
`blueconfigs/sonataconf-quick-multiscale`.

## Testing
The existing `tests/scientific-ngv`.

## Review
* [x] PR description is complete
* [x] Coding style (imports, function length, New functions, classes or
files) are good
* [ ] Unit/Scientific test added
* [ ] Updated Readme, in-code, developer documentation
